SHEETLIKE PLASTER

机译:雪利膏

摘要

PROBLEM TO BE SOLVED: To obtain a sheetlike plaster capable of readily evaporating water or the like coated at the time of application and shortening the drying time without a sticky feeling at a low cost by arranging an application layer composed of a wet tacky composition and a holding layer in a specified structure. ;SOLUTION: This sheetlike plaster comprises an application layer 20 composed of a wet tacky composition and a holding layer 10 for holding the application layer 20 and is obtained by arranging the application layer 20 so as to expose a part of the application layer 20 to the side of a nonapplication surface of the holding layer 10. The exposed area of the application layer 20 is preferably 10-60% based on the plane area of the sheetlike plaster. The holding layer 10 is preferably a netlike woven or nonwoven fabric. (A) Polyvinylpyrrolidone or/and a polyvinylpyrrolidone-vinyl acetate copolymer, (B) a liquid plasticizer compatible with the ingredient A and (C) a filter are preferably contained in the wet tacky composition. Since the plaster provides the holding layer 10 in a state thereof firmly entering the application layer, the mechanical strength is increased and peeling residues are hardly caused.;COPYRIGHT: (C)1999,JPO
